When you use one of Emacs’ help commands, another window will open with the documentation. You can use C-M-v and C-M-V to scroll the other window down and up respectively to read the help, without having to switch to that window.

This is a bit of a niche post but I recently found I had accidentally started a bunch of duplicate timers all running the same function. I hadn’t recorded the timer objects for them so couldn’t use cancel-timer to kill them. After a bit of searching I discovered the function cancel-function-timers which will cancel all timers that call a particular function.

The *scratch* buffer is useful for dumping temporary bits of text, or trying out bits of lisp code. By default the contents are not saved, but it can be handy to have the scratch buffer saved and restored when you start a new Emacs session. This is easy with the persistent-scratch package, just add the following to your emacs config file:

This post was originally titled “Prevent Emacs wiping the system clipboard”, which was a rubbish description of what this tip actually covers, so I renamed it! Apologies if you see it twice in your RSS reader.

By default, if you copy something to the system clipboard (e.g. some text in firefox) and then copy or kill some text in Emacs, then the text from firefox is lost. If you set the option below in your emacs config file then copying or killing text in Emacs will add the system clipboard text to the kill-ring so that you can find it when you cycle through your clipboard history in Emacs.
